Help me with this vocabulary pleaseee

Answer 1

Note: I have provided my own definition for the ninth term (firn) in the third image for which the definition was missing

Answer:

A. 1. The height of anything above a given planetary reference place, especially above sea level on Earth, the extend of distance upward - altitude

2. The movement of glacial ice and snow as a result of gravity - basal slip

3. When chunks of ice break off at the terminus, or end of a glacier - calving

4. An amphitheater like valley formed by glacial erosion - cirque

5. A long period of cold climate where glaciers cover large parts of the earth - ice age

6. Miniature ice sheet - ice cap

7. The angular distance of a place north or south of the Earth’s equator usually expressed in degrees and minutes - latitude

8. The study of the Earth’s atmosphere in prehistoric times - paleoclimatology

9. Below the surface in the region under enough pressure that the ice is no longer brittle the ice distorts and changes shape due to the pressure of the above layers - plastic flow

10. When a glacier loses more snow and ice due to melting and calving than it accumulates - glacial retreat

B.   1. A deep crack or area of cracks that result from the upper layer of the glacier ice breaking when the lower layer of ice flows - crevasses, aka zone of fracture

2. Snow accumulation converted into granular ice over time - zone of accumulation

3. A boulder left behind by a glacier - glacial erratic

4. Scratches or gouges cut into bedrock by glacial abrasion or rubbing - glacial grooves or striations

5. Unsorted sediment deposited directly when glacial ice melts - moraine

6. A pile of rocks left behind by a glacier - glacial till

7. The location on a mountain glacier when the rate of accumulation is equivalent to the rate of melting - snowline or equilibrium line

8. the terminus or down-slope end of the glacier where ice and snow are melting faster than accumulating  - zone of ablation (or wastage)

9. Firn = crystalline or granular snow that has not yet been compressed into ice. If is found especially on the upper part of a glacier
